INTERNAL-COMBUSTION moron.

Application filed April 5, 1921. Serial No. (58,782.

' employed.

One object of the invention is to provide, in an internal combustion motor, a. rotatable valve which -fits around the cylinder head and is provided with a port adapted to register successively with the intake and exhaust ports of the cylinder heads.

Another object of the invention is to provide, in an internal combustion motor, having a plurality of cylinders and sleeve-like rotatable valves which fit around the cylinder heads and which are operated from the motor crank shaft, each valve having a port 5 adapted to re ister with the intake and ex-.

haust ports 0 the res ective cylinders, the that the operation as compared to the ordinary poppet valve,

or other types of valves now in common use.

A further feature of the invention resides in the novelly formed and arranged intake and exhaust manifolds.

A still further feature of the invention resides in the revision of a cylinder whose head is special yformed to receive and protect the spark plugs, in the manner hereinafter stated.

With the above and other objects in view the invention has-particular relation to certain novel features of construction, operation and arrangement of parts, an example of whichis given in this specification andv illustrated in the accompanying drawings, wherein a Figure 1- is a side view of the motor, partially in section, and

Figure 2 is a transverse sectional view. Referring now' more particularly to the drawings, the numeral 1 designates the motor as awhole,-which is provided with a plurality of c linders 2, said cylinders being formed wit surrounding water jackets, thus making provision for cooling the same. The numeral 3 designates the crank shaft cylinder.

and the numeral 4 designates the piston. Each piston is connected to the crank shaft through the usual connecting rod '5. The outer end of each cylinder-is concave in general contour and is formed with an upstanding annular flange 6 forming a housing of the spark plug 7, which is threaded into the cylinder head. A jacket 8 surrounds andis spaced from the flange 6, forming a chamber between them for the circulation of water to keep the spark plug relatively cool. The cylinder head has a tapering or conical-shaped section 9, around which a similarly shaped valve 10 works,

which water is circulated. An enclosing cap .12 is bolted onto the head 11 to enclose and rotect the working parts. Each cylinder ead has the oppositel disposed intake and exhaust ports 13 an 14 and each valve has a single port 15 adapted to register with the cylinder ports. Formed in the head 11 are the intake and exhaust manifolds 16 and 17, which are connected with the cylin der through the respective conduits 18 and 19 arranged to align with the respective ports 13 and 14. Fixedupon the crank shaft 3 there is a pinion 20 in mesh with a similar pinion 21 which is fixed on the lower end of the shaft 22. The upper end of this shaft has the. procket wheel 23 fixed thereon, which is in alignment with a similar sprocket wheel 24, which is fixed on the valve sleeve and the latter is driven from the former through a suitable sprocket chain 25. The valves are thereby driven from the crank shaft 3 and are timed so that the valve port will register at the proper time with the intake and, exhaust ports of the The valves are thereby driven in a practically noiseless manner and the 'working parts are all protected from forcombination with a cylinder whose outer end is convex in general contour and formed with an upstanding annular flange forming a spark plug housing, of a rotary member around said outer end of said cylinder, the upper part of said member being sleeve-like in form and fitting around said housing, and the lower part thereof being flared forming a valve "which works around the convex end of the cylinder, a cylinder head fitted onto said cylinder and provided with a bearing for said sleeve, an enclosing cap bolted onto said head and inclosing and 'protecting the working parts, said head being provided with oppositely disposed intake and exhaust ports, and said valve having a single port adapted to register with the head ports successively, an intake and an exhaust manifold formed in the head, said head being rovided with conduits, said manifolds being connected with the cylinder through said ports and conduits, and operative connections between the motor crank shaft and valve to rotate the latter. I

2. An internal combustion motor including a cylinder whose outer end is formed with an upstanding annular flange forming a spark plug housing, a rotary member working around said flange and Whose lower end is flared forming a valve around "said cylinder end, the upper end of said member being formed into a sleeve which fits around said housing, a cylinder head fitted onto said cylinder and provided with a suitable bearing for the valve sleeve, a cap on said head enclosing and protecting the Working parts,

said head-being provided with spaced intake and exhaust ports, and said valve having a single port adapted to register with the cylinder ports successively, said head being provided with conduits and manifolds I HOARD LEE.
